Produktinformationen "XS15 - Pam3Cys-GDPKHPKSF"

The adjuvant XS15 is a water-soluble TLR2/TLR1 ligand inducing strong CD8 and TH1 CD4 response against free short peptides emulsified in Montanide™ ISA 51 after a single s.c. injection. It was shown that the granuloma induced by injection of a mixture of short synthetic peptides and Montanide™ shows high concentration of functional antigen specific T-cells that produce IFNy, TNF, and IL2, CD8 cells also produce CD107a, but no IL10 [1]. High frequencies of antigen specific T-cell were also found in the peripheral blood. XS15 supports potent T-cell response in a COVID-19 peptide vaccine [2,3].

The lipopeptide is provided as a endotoxin-free, lyophilised, colourless powder without any additives. It can be shipped at room temperature an the lyophilized powder should be stored at +2°C to +8°C. XS15 can be reconsituted in endotoxin-free water (1mg/mL stock solution). 

XS15 is recommended for immunisation in combination with Montanide™ IA 51 (SEPPIC GmbH Köln, Germany) [4] to generate a strong immune response against free short peptides.

Recommendation for immunising mice: 300µg antigen plus 50µg (1mg/mL solution) Adjuvant XS15 plus 100µL Montanide™ ISA 51.
